Dynamics of capillary coalescence and breakup: Quasi-two-dimensional nematic and isotropic droplets

Coalescence and Breakup of Oppositely Charged Droplets

The coalescence process of oppositely charged drops for different electrical conductivities of liquids is presented. When the electrical conductivity was relatively low, oppositely charged drops failed to coalesce under sufficiently high electrical fields and capillary ripples were formed on the surfaces of droplets after rebound. For a high electrically conductive liquid, it was found that a c...

Electro-capillary instability of a nematic-isotropic interface

We have studied the morphological instability under AC electric field of a nematicisotropic interface confined between two electrodes set at different temperatures. The electrodes are treated for homeotropic anchoring so that, when the field is increased, the Ericksen elastic stress vanishes. In this limit, the instability resembles that observed in ordinary liquids. However, significant differ...

Drop deformation, breakup, and coalescence with compatibilizer

The effect of copolymers on the breakup and coalescence of polybutadiene ~PB! drops in polydimethylsiloxane ~PDMS! is studied using a four-roll mill flow cell. Copolymers are produced at the interface by a reaction between functionalized homopolymers. They reduce the interfacial tension and thus enhance breakup; they also inhibit coalescence of drops. Under the conditions of our experiments, th...
